Card dispenser

ABSTRACT

A card dispenser for dispensing a rewritable card is disclosed herein. The card dispenser may include a card feeder for receiving or dispensing a rewritable card. In addition, the card dispenser includes a roller assembly for moving the card from the card feeder to components within the card dispenser; a processor for receiving card data via a short-range wireless connection with a mobile device of a user, the card data including (i) a card identifier of a plurality of card identifiers associated with an account of the user and (ii) a unique derivation key for encrypting the card identifier; and a card writer for powering an electrophoretic display of the card, causing at least a portion of the card data to be rendered on the display, and stopping the powering of the display.

BACKGROUND

Card systems have been used in many industries. For example, the hotel industry uses card systems to assign key cards to hotel rooms to enable customers to open hotel rooms using key cards instead of using keys. Once the customer has checked out of the room, the key card can be reassigned to another room. Furthermore, financial institutions use card systems to generate bank cards, credit cards, and other cards to enable customers to interact with their accounts. Some card systems include the ability to create temporary cards that are valid only under specific conditions (e.g., for a given period of time). Card providers may use card printers at their premises to create the required cards. Card printers generally process new cards. The processing of the new card may include printing on a surface of the card. Thus, to acquire a temporary card, a customer is generally required to contact the card provider, and the card provider may issue a temporary/new card to the customer in the same manner as a regular card is issued. In many situations, the customer must go through various people and wait for a prolonged period of time (e.g., 7-10 days) before the card is received and maybe used. This may not be acceptable to the customer and the customer may use other means to perform the task that the card performs.

SUMMARY

In some embodiments, to solve this problem, methods, apparatuses, and/or a self-service card dispenser system are disclosed herein that enable a card dispenser to communicate with a device of a user to dispense a card associated with an account of the user. That is, upon request, based on the data received from the device of the user, a card dispenser generates and dispenses, to the user, a card associated with the user's user account.

In some embodiments, the card dispenser may detect a device of a user (e.g., via a short-range wireless connection) and receive, from that device, card data for printing information onto a card received in the card dispenser. The device of the user may have an installed application that interfaces with the systems of the card provider. The application may store account information associated with the account of the user corresponding to the card provider. For example, if a card provider is a hotel, the application may be interfacing with the hotel's computer systems (e.g., servers) that store user account information. Thus, the application may request and/or store account information associated with the particular user.

A user may insert a card into a device associated with the card dispenser (e.g., a user may reuse a card in the user's possession), or the card may be inserted into the card dispenser by a device coupled with the card dispenser (e.g., a new card may be dispensed to the user). The user may select an option within the application for generating a new or temporary card. For example, the user may want to generate a temporary credit card for credit card transactions or a hotel card for being able to enter the hotel and open a hotel door. When the device of the user receives the selection, appropriate card data may be received at the user device from, for example, the server(s) of the card provider. When the card data is received at the device of the user, the card data may be transmitted to the card dispenser. The card data (e.g., received from the device of the user) may include (i) a card identifier associated with an account of a user and (ii) an encryption key for encrypting the card identifier. As an example, the encryption key may be a unique derivation key for encrypting the card identifier, where the key is derived from a unique master key (e.g., associated with the user account). Furthermore, the card data may include a plurality of card identifiers associated with the account of the user. Each identifier may be received along with a unique derivation key for encrypting the card identifier.

The card dispenser may power an electrophoretic display of the card, overwrite the card data on a memory of the card, and cause at least a portion of the card data to be rendered on the display of the card. The card dispenser may stop the powering of the display, subsequent to which, rendering of the portion of the card data remains on the display of the card. At this point, the card may be dispensed to the user. Thus, the card dispenser performing these actions may be a part of a self-service process where a user may receive a card (e.g., a temporary card or a new card).

In some embodiments, the card dispenser may include a card feeder for receiving or dispensing the card; a roller assembly for moving the card from the card feeder to one or more components within the card dispenser and back to the card feeder; and a card writer for overwriting the memory of the card with the card data.

Various other aspects, features, and advantages of the invention will be apparent through the detailed description of the invention and the drawings attached hereto. It is also to be understood that both the foregoing general description and the following detailed description are examples and not restrictive of the scope of the invention. As used in the specification and in the claims, the singular forms of “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. In addition, as used in the specification and the claims, the term “or” means “and/or” unless the context clearly dictates otherwise.

DETAILED DESCRIPTION

In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the invention. It will be appreciated, however, by those having skill in the art that the embodiments of the invention may be practiced without these specific details or with an equivalent arrangement. In other cases, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring the embodiments of the invention.

FIG. 1 shows an example of a card dispenser 100, in accordance with one or more embodiments. Card dispenser 100 may be configured to receive a card at an input area, write a card identifier or other card data to the card, and dispense the card after writing the card data to the card. As an example, the card data may include (i) one or more card identifiers associated with a user account (e.g., one or more virtual card numbers associated with the user account), (ii) one or more encryption keys for encrypting one or more pieces of the card data (e.g., unique derivation keys or other keys for encrypting the card identifiers or other data), (iii) one or more card use parameters (e.g., parameters defining one or more restrictions or other features of the card related to usage of the card), or (iv) other data.

As shown in FIG. 1, in some embodiments, card dispenser 100 may include card feeder 110, transport assembly 140, card writer 150, controller 170, or other components. Some or all components of the card dispenser 100 may be operatively coupled and included in an enclosure (not shown). In some embodiments, some or all components of the card dispenser are not collocated (e.g., are not within a same enclosure, or in a same physical location). Card dispenser 100 may be configured to receive a card 190. Card 190 may be moved within components of card dispenser 100, where it is processed and dispensed. As an example, the processing may include communicating with computing components on the card. For example, some cards include microchips that are able to store information including a card number (e.g., an encrypted card number) as well as other identifying information. In addition, the processing may include an authenticating process so that unauthorized car dispenser systems are not able to overwrite data on cards. In some embodiments, the authenticating process may be mutual so that unauthorized cards are not able to gain access to the provider's system. The authenticating process may use public/private key infrastructure (PKI) or another suitable authenticating process.

In some embodiments, the card may include a rewritable memory area for storing data that can be retrieved or otherwise read. For example, the card may include an electrophoretic display that will hold a static image, even without electricity—when there is no change in image or text, the electrophoretic display presents the last content uploaded and will hold it in perpetuity. The electrophoretic display may consume power only when the content on it is changing. Thus, the electrophoretic display is extremely energy efficient and may be capable of running for months on a single battery charge. The card dispenser may store card data on the card and render a portion of the card data on the electrophoretic display of the card.

In some embodiments, card 190 may include circuitry 195, a display 198, or other components. Circuitry 195 may provide information processing and communications capabilities within card 190, or between card 190 and card dispenser 100 or other systems (e.g., server system 250, or point-of-sale terminal 290 described herein). Card dispenser 100 may be configured to receive card 190 and power circuitry 195. For example, circuitry 195 may be powered by contact with the card dispenser (e.g., electrical connection between the circuitry and card dispenser). In another example, circuitry 195 may be wirelessly powered without physical contact with the card dispenser (e.g., via antennas of circuitry 195 and radio frequency signals from card dispenser 100, powering via inductive coupling, etc.).

Circuitry 195 may include a processor, a memory, or other components. For example, card data received by card dispenser 100 may be stored in the memory of circuitry 195, and a portion of the card data may be rendered on display 198. In some embodiments, circuitry 195 may be embedded in card 190. In some embodiments, circuitry 195 may include a microchip, a magnetic strip, a barcode, Quick Response (QR) code, an RFID tag, a communication device (e.g., Near Field Communication (NFC) antenna, Bluetooth® device, or WiFi device), or other electronic components.

Card dispenser 100 may communicate with circuitry 195 to authenticate the card or the user. As an example, after receiving the card, card dispenser 100 may request authentication of the card before processing the card (e.g., storing information, rendering information, etc.). In some embodiments, circuitry 195 may generate a cryptogram from security data previously encoded in circuitry 195 (e.g., by the card issuer), and send the cryptogram along with a digital certificate (from the issuer) to the card dispenser for verification of authenticity of the card by the card dispenser.

Card dispenser 100 may be configured to authenticate the user in various ways. For example, card dispenser 100 may use multi-factor authentication, PKI, or another suitable authentication method. In some embodiments, card dispenser may authenticate the card or the user using proximity of a user device (e.g., a mobile phone). That said, other methods of authenticating the card by the card dispenser 100, or the user are contemplated within the scope of the present disclosure.

Circuitry 195 may be configured to store card data received by card dispenser 100. In some embodiments, card dispenser 100 may read previous information that was previously stored on circuitry 195 (e.g., in the case of a card that is being re-used) before storing the card data. For example, card dispenser 100 may be configured to overwrite the previous information, keep all the previous information and add the card data, or keep some of the previous information and add the card data. Furthermore, card dispenser 100 may be configured to determine what information to keep and what information to overwrite (e.g., by comparing the previous information and the card data). For example, the previous information may include generic information about the card issuer, contact information, instructions for basic function of circuitry 195, or other generic information, that the card dispenser may determine not to overwrite.

In some embodiments, card data received by card dispenser 100 and stored on circuitry 195 may include a card identifier associated with an account of the user. The card identifier may be used to authenticate the card (e.g., after it is dispensed by the card dispenser 100). The card data may include a unique derivation key for encrypting the card identifier. For example, the unique derivation key may be derived from a unique master key (e.g., of the issuer, associated with the user account, etc.). Furthermore, the card data may include a plurality of card identifiers associated with the account of the user. Each identifier may be received along with a unique derivation key for encrypting each card identifier. In addition, card data stored in circuitry 195 may include other security information that may allow the card to be securely used after its dispensed from card dispenser 100. For example, card data may include applications, programs, requirements, or instructions from the card issuer for generating session keys and cryptograms that are unique to the card 190 to be used during transactions (e.g., for authentication or authorization of transactions with the card issuer).

In some embodiments, card data received by card dispenser 100 and stored on circuitry 195 may include one or more card use parameters that define usage of the card after the card dispensed by card dispenser 100. In addition, the card use parameters may be determined by the user, the card issuer, or the card dispenser. Furthermore, the card data may include a plurality of card identifiers that are each associated with a use parameter. For example, the use parameter may define one or more time periods during which use of the card is permitted or prohibited, locations at which use of the card is permitted or prohibited, services or users for or by which use of the card is permitted or prohibited, or other restrictions or use parameters for using the card. In some embodiments, the card use parameters may be defined by the user (e.g., using a user device). As an example, the card use parameters may be defined by an application residing on the user device. For example, when the application on the user device receives a request for dispensing a new card, the application may transmit a request to a card provider (e.g., to one or more servers at the card provider) for data for generating new/temporary card. The user device may receive the card data along with the card use parameters.

In some embodiments, the card use parameters stored in circuitry 195 may include an expiration date, a location (e.g., a specific building, floor, garage, office, lab, etc.), a geographic area (e.g., a specific city, state, country, etc.), a type of business where the card is valid, or other use parameters. The use parameter(s) may be determined by the user (e.g., via a user interface of the user device or the user interface of the card dispenser), by the issuing entity, or another entity. For example, the issuing entity may be a government entity, an employer, a business, a financial institution, or another suitable issuing entity. The cards dispensed by card dispenser 100 may be used for different purposes. For example, the cards may be ID cards, transactional cards, credit cards, bank cards, phone cards, passports, driver's licenses, network access cards, employee badges, security cards, visas, immigration documentation, citizenship cards, social security cards, security badges, gift cards, or other types of cards.

In some embodiments, a portion of the card data received by card dispenser 100 and stored in circuitry 195 may be rendered on the card. For example, a portion of the data may be rendered on display 198, and another portion may be rendered on the surface of the card in a different manner (e.g., printed on the card). In some embodiments, the card dispenser 100 may determine the portion to be rendered on the display based on the type of display, size of the display, or other features of the display. Card dispenser 100 may receive instructions indicating which portion of the card data should be rendered on the display (e.g., from server system 250 or from the user).

In some embodiments, card dispenser 100 may be configured to overwrite previous display information, keep all the previous display information and add a portion of the card data, or keep some of the previous display information and add a portion of the card data. Card dispenser 100 may be configured to determine which information to keep and which information to overwrite (e.g., by comparing the previous display information and the card data). For example, the previous display information may include generic information about the card issuer, contact information, card holder, or other generic information, that the card dispenser may determine to keep.

In one example, card dispenser 100 may be configured to power display 198, render the portion of the card data on the display, and power the display off such that the portion of the data remains on the display after the power is turned off. For example, display 198 may be an electrophoretic display configured to display the portion of the data without requiring power. In some embodiments, the portion of the card data may remain on the display until it is overwritten (e.g., by card dispenser 100).

In another example, card dispenser 100 may be configured to power display 198, render a portion of the card data on the display, and power the display off such that the portion of the data does not remain on the display after the power is turned off. In some embodiments, the data is presented back on the display responsive to the circuit 195/display 198 being powered on. For example, circuit 195 may be turned on responsive to the card being in proximity of a user's device, point-of-sale terminal 290, or the card dispenser 100 (e.g., using radio frequency). The card may be then authenticated (e.g., via multiple-factor authentication), after which the display is turned on and the data is presented on the display.

In some embodiments, card dispenser 100 may be configured to render data on the surface of the card. For example, a portion of the card data may be printed on one or more outer surfaces of the card. This action may be performed using one or more card printing techniques, including thermal transfer using color ribbons, dye diffusion thermal transfer, laser printing, ink jet, reverse image transfer techniques, stamping, embossing, water mark techniques, or other printing (or writing) techniques. In some embodiments, card dispenser 100 may determine an appropriate technology for different types of data to be printed. Furthermore, card dispenser 100 may be configured to overwrite or erase some or all previously printed information. Card dispenser 100 may also be configured to determine which printed information to keep and which information to overwrite (e.g., by comparing the previously printed information and the card data).

In some embodiments, card dispenser may include card feeder 110 for receiving the card and feeding the card into card dispenser 100. Card feeder 110 may be operatively connected to transport assembly 140 for transporting cards within card dispenser 100. Card feeder 110 may be configured to dispense the card. For example, after processing by card dispenser 100, a card may be transported back to card feeder 110 for dispensing. In some embodiments, card feeder 110 may be configured for reading information from the card (e.g., via a card reader in the card feeder 110). Furthermore, card feeder 110 may be configured to power circuitry 195 of the card (e.g., by electrical connection between the circuitry and card dispenser, or via antennas of circuitry 195 and radio frequency signals from card feeder 110). In some embodiments, card feeder 110 may communicate with circuitry 195 to authenticate the card or the user. As an example, after receiving the card, card feeder 110 may request authentication of the card before processing the card (e.g., storing information, rendering information, etc.). In response to the authentication request, circuitry 195 may generate a cryptogram from security data previously encoded in circuitry 195 (e.g., by the card issuer), and send the cryptogram along with a digital certificate (from the issuer) to card feeder 110 for verification of authenticity of the card by the card feeder 110. In addition, card dispenser 100 may be configured to authenticate the card or the user (e.g., via multi-factor authentication, proximity of a user device, etc.).

In some embodiments, the card feeder 110 may be in the form of a card slot, a card tray, or another card receptacle for receiving a card and providing the card to the card dispenser 100 for further processing. Card dispenser 100 may include a card supply storage 120 for storing and supplying one or more cards to be processed by card dispenser 100. In some embodiments, card supply storage 120 may be operatively connected to card feeder 110 or to transport assembly 140 for transporting cards within card dispenser 100. In addition, card supply storage 120 may store “blank” cards that have not been used before or have generic or no data on them. For example, responsive to a request for a new card in instances where a card is not provided through card feeder 110, a card is supplied from card supply storage 120. In some embodiments, card supply storage 120 may be in the form of a tray, a cassette, a receptacle, or another type of card storage for holding cards. Card supply storage 120 may include a card pusher, a loaded spring, clamps, suction cups, or other mechanisms for moving a card from card supply storage 120 to transport assembly 140.

In some embodiments, transport assembly 140 may be configured to move card 190 from card feeder 110 or card supply storage 120 to one or more components within card dispenser 100. The transport assembly 140 may be configured to move the card back to card feeder 110 (e.g., after processing by card dispenser 100). Transport assembly 140 may be operatively connected to one or more components of card dispenser 100 (e.g., card feeder 110, card supply storage 120, card writer 150, card output 160, controller 170, or other components). In some embodiments, transport assembly 140 may include a roller assembly, moving receptacles, belts, pulleys, or other transport mechanisms for moving the card within the card dispenser 100.

Card writer 150 may be configured to receive a card from card feeder 110 or card supply storage 120 via transport assembly 140 and store or render card data (received by card dispenser 100). For example, card writer 150 may be configured to receive card data to be written on the card. Card writer 150 may receive the card data in a variety of ways. For example, card data may be received from server system 250 (shown in FIG. 2 and described herein). In another example, card data may be received via a user device of the user (e.g., mobile device). In yet another example, card data may be received from the user device using radio frequency, Near Field Communication (NFC), Bluetooth®, WiFi, or other contactless manner. In some embodiments, card data may be received by controller 170 and transmitted to card writer 150.

Card writer 150 may be configured to receive card 190 and power circuitry 195. In some embodiments, card writer 150 may power circuitry 195 by contact with the card (e.g., electrical connection between the circuitry 195 and card writer 150). While in some embodiments, card writer 150 may power circuitry 195 without physical contact with the circuitry (e.g., radio frequency signals from card writer 150 and antennas of circuitry 195). Card writer 150 may be configured to store information (card data) in card circuitry 195 in a logical manner. For example, on a microchip, a magnetic strip, a barcode, Quick Response (QR) code, an RFID tag, or another component or components of circuitry 195 of the card. In some embodiments, card writer 150 may use different techniques to write (store) data in circuitry 195 of the card. For example, in some cases, card writer 150 may include a conductive plate for transferring information to and from circuitry 195. In some embodiments, the card writer 150 may be configured to transfer information in a contactless manner (e.g., by using radio frequency, Near Field Communication (NFC), Bluetooth®, WiFi, or other contactless manner). Furthermore, card writer 150 may be configured to encode information onto a magnetic stripe of the card (e.g., by modifying magnetism of iron- based magnetic particles). That said, other techniques for transferring data from card writer to the card circuitry are contemplated within the scope of the disclosure.

In some embodiments, card writer 150 may communicate with circuitry 195 to authenticate the card 190 or the user. As an example, after receiving the card, card writer 150 may request authentication of the card before transferring or rendering data. For example, card writer 150 may read previous information that was previously stored in circuitry 195 (e.g., in the case of a card that is being re-used) before storing the card data, and may overwrite the previous information, keep all the previous information and add the card data, or keep some of the previous information and add the card data. In some embodiments, card writer 150 may be configured to determine which information to keep and which information to overwrite (e.g., by comparing the previous information and the card data). For example, the previous information may include generic information about the card issuer, contact information, instructions for basic function of circuitry 195, or other generic information, that card writer may determine to keep, while determining to overwrite previous account information (e.g., because the previous account information is associated with a previous user).

In some embodiments, card writer 150 may be configured to store (e.g., in circuitry 195 of card 190) card data that includes a card identifier associated with an account of the user, a unique derivation key for encrypting the card identifier, applications, programs, requirements, or instructions from the card issuer for generating session keys and cryptograms that are unique to card 190 (e.g., for authentication or authorization of transactions with the card issuer). Furthermore, card writer 150 may be configured to store one or more card use parameters on the card (e.g., parameters that define usage of the card after the card is dispensed by card dispenser 100). In some embodiments, card writer 150 may be configured to store the card use parameters that define time, location, services, users, restrictions, or other parameters for using the card. For example, the card use parameters may include an expiration date, a location (e.g., a specific building, floor, garage, office, lab, etc.), a geographic area (e.g., a specific city, state, country, etc.), a type of business where the plastic is valid, or other use parameter.

In some embodiments, card writer 150 may be configured to cause a portion of the card data received by card dispenser 100 and stored in circuitry 195 to be rendered on the card 190. For example, card writer 150 may be configured to program the card 190 so that the card 190 is programmed to render a portion of the data on display 198. Additionally or alternatively, card writer 150 may render the portion of the data on another portion on the surface of the card in a different manner (e.g., printed on the card 190). In some embodiments, card writer 150 may determine the portion of data to be rendered on the display based on the type of display, size of the display, or other features of the display. For example, card writer 150 may receive instructions indicating which portion of the card data is to be rendered on the display (e.g., from server system 250 or from the user). In some embodiments, card writer 150 may be configured to overwrite previous display information, keep all the previous display information and add a portion of the card data, or keep some of the previous display information and add a portion of the card data. Card writer 150 may be configured to determine which information to keep and which information to overwrite (e.g., by comparing the previous display information and the card data). For example, the previous display information may include generic information about the card issuer, contact information, card holder, or other generic information, that the card writer 150 may determine to keep.

In some embodiments, card writer 150 may be configured to power display 198, render the portion of the card data on the display, and power off the display such that the portion of the data remains on the display after the power is turned off. For example, display 198 may be an electrophoretic display configured to display at least a portion of the card data without requiring power. In some embodiments, the portion of the card data may remain on the display until that data is overwritten (e.g., by card writer 150).

In some embodiments, card writer 150 may be configured to power display 198, render a portion of the card data on the display, and power off the display such that the portion of the data does not remain on the display after the power is turned off. For example, the data may be presented back on the display responsive to circuitry 195/display 198 being powered on. In another example, responsive to the card being in proximity of a user's device, or point-of-sale terminal 290 (or the card dispenser 100), circuitry 195 may be turned on (e.g., using radio frequency). The card may then be authenticated (e.g., via multifactor authentication), after which the display may be turned on and the data presented on the display.

In some embodiments, card writer 150 may be configured to render data on the surface of the card. For example, card writer 150 may be configured to print a portion of the card on one or more outer surfaces of the card. Card writer 150 may use one or more card printing techniques including thermal transfer using color ribbons, dye diffusion thermal transfer, laser printing, ink jet, reverse image transfer techniques, stamping, embossing, water mark techniques, or other printing (or writing) techniques. In some embodiments, card writer 150 may determine an appropriate technology for various data to be printed (e.g., thermal printing issuer's name, contact info, Card Verification Value (CVV), etc.; embossing user's name, expiration date, etc.; or stamping a water mark). In some embodiments, card writer 150 may be configured to overwrite or erase some or all previously printed information. Card writer 150 may be configured to determine which printed information to keep and which information to overwrite (e.g., by comparing the previously printed information and the card data).

In some embodiments, card output 160 may be configured to dispense card 190. Card output 160 may be operatively connected to transport assembly 140, card writer 150, card feeder 110, controller 170, or other components of card dispenser 100. In some embodiments, card output 160 may be configured to receive card 190 after being processed by card writer 150. For example, card output 160 may be configured to read card data on the card before dispensing the card. In some embodiments, card output 160 may be configured to power the card 190, read the card data from the card 190, compare the data on the card 190 with the card data received by card dispenser 100 (to be written on the card 190), and dispense the card 190 responsive to the data on the card 190 matching the card data. In some embodiments, responsive to the data not matching, card output 160 may be configured to return the card 190 to card writer 150 (e.g., for rewriting) or for discarding the card 190. Card output 160 may be in the form of a slot, a tray, a tube, or receptacle for dispensing the card. In some embodiments, some or all operations performed by card dispenser may be performed by card feeder 110. For example, transport assembly 140 may be configured to transport the card 190 from card writer 150 back to card feeder 110 for dispensing.

It should be appreciated that the description of the functionality provided by the different components of card dispenser 100 described herein is for illustrative purposes, and is not intended to be limiting, as any of components of card dispenser 100 may provide more or less functionality than described. For example, one or more of components 110, 120, 140, 150, or 160 may be eliminated, and some or all of their functionality may be provided by other ones of the components of card dispenser 100. As another example, additional subsystems may be configured to perform some, or all of the functionality attributed herein to one of the components of card dispenser 100.

In some embodiments, controller 170 may be configured to manage one or more operations of card dispenser 100. For example, controller 170 may be configured to transfer information, instructions, or signals to operate components 110, 120, 140, 150, and 160.
